i got 3 plants a couple wk from finish and the 600 watt hps blowed.
i put the mh in. no locals so must order one.
will this effect the plants under mh ?
btw, 600w switchable cooltube from yes.com, 1st use and bulb failed.
It will not be a problem. There are some that switch over to a MH the last 2 weeks or so of flowering because they believe that it gives you tighter nugs and more resin. The MH will run somewhat hotter and put out less lumens than the HPS, but it will work just fine.
I've had problems with yescomusa stuf as well. Bulb burnt out within a couple of days and I had to take the whole unit down to replace bulb as the unit was warped in shipping, the first unit was damaged beyond help in shipping. Cheap products packed poorly and terrible customer service.
